Subject: [PATCH] Fix revparsing with windows paths in blame example

`revparse_single` uses a git object name and not a file path - that means backslashes must be translated to slashes on windows.
Otherwise the example fails:
```
E:\dev\git2-rs>.\target\debug\blame.exe examples\blame.rs
error: the path 'examples\blame.rs' does not exist in the given tree; class=Tree (14); code=NotFound (-3)
```
I reused the `cfg!` conditional from `remote.rs`, but there might be a better way to do that.
